--- Comment #1 from Rafał Mużyło galtgendo@o2.pl --- Given the error, I'm assuming you're still using x11 wine driver (I'm not sure if wayland one is already in a working condition).
So, would you add 'x11drv' channel to the log ?
(also, 'xset dpms force off' can be used to trigger the blankout immediately in xorg, not sure how to trigger that in wayland, but there likely *is* a simple way)
